Photo 3/19 | 1301tr 02 Ultimate Ford F 150 Trailer Hitch Before Measurement | 1. We began the install by measuring the factory ride height of the trailer hitch ball. Keep in mind this truck is also equipped with a Ready Lift 1.5-inch rear lift block to achieve a true leveling kit. The before number came in at 20 inches.

Photo 10/19 | 1301tr 01 Ultimate Ford F 150 Firestone Wireless Command Center II System | 8. Here you can see the Firestone Wireless Air Command II system (PN: 2540, $699.99). For our work truck, we wanted something fast and easy. The kit included an awesome wireless digital controller with LCD air pressure readout and it also doubled as a LED flashlight. Pretty trick stuff.

Photo 11/19 | 1301tr 01 Ultimate Ford F 150 Air Compressor | 9. The air compressor was mounted inside the bedwall under the truck. We made sure to mount it away from heat and moving parts.

Photo 12/19 | 1301tr 01 Ultimate Ford F 150 Air Compressor Power Source | 10. Running from the compressor to the front of the truck where the battery was mounted, the wiring was a breeze with wire connections needed for only 12V power, ground, and ignition source.

Photo 15/19 | 1301tr 01 Ultimate Ford F 150 Air Filter | 13. This air compressor filter was then run to an elevated mounting position to keep water out of the compressor.

Photo 16/19 | 1301tr 01 Ultimate Ford F 150 Mounting Spacer | 14. With everything dialed in, we then slipped this airbag mounting spacer in between the airbag and lower mount. We could then bolt down the airbag to the lower mount.

Photo 18/19 | 1301tr 01 Ultimate Ford F 150 Wireless Controller | 16. Inside the truck, we could scroll up and down to adjust the rear height based on our towing and hauling weight. The wireless controller also had three memory settings for regularly towed trailers.

Photo 19/19 | 1301tr 01 Ultimate Ford F 150 Trailer Hitch After Measurement | 17. Once the compressor filled the airbags to the max, we measured the top of hitch ball and the final tally was 25 ½ inches, or an increase of 5 ½ inches. This will help provide a huge boost for towing and hauling. Say goodbye to a sagging truck struggling to tow a trailer.
